Jesus seen from the angels

"Unquestionably, the mystery of godliness is great : God was manifested in the flesh, was justified in the Spirit, was seen from the angels, was preached among the nations, was believed in the world, was raised in glory . "1 Timothy 3. 16

 
All the earthly life of our Lord Jesus took place under the gaze of angels. He was "seen" angels. The verb means to "see", "to visit", "to observe", sometimes to "assist". Indeed, throughout the earthly ministry of the Lord, the angels watched him and they assisted him on certain occasions.
The angels announced his birth to Joseph and the shepherds. They are present to contemplate the mystery of the Son of God become a baby lying in a manger.
Later, in the desert, they approach him and serve him after he alone resisted the temptations of the devil.
In Gethsemane, when the Lord is in the anguish of battle, an angel of heaven strengthens him (Luke 22:43).
At the resurrection, angels are there (Luke 24: 4, 5), the one who rolled the stone at the entrance to the tomb (Matt. 28: 2) ; Those who appeared to women to tell them that Jesus was risen (Luke 24: 4-7). Two angels are present at the moment when the Lord Jesus ascends to heaven (Acts 1:11).
The angels have seen it : indeed they have played a part in the earthly life of our Lord, and this from beginning to end. But during the three hours of darkness at Golgotha, Jesus was alone, absolutely alone, faced with the anger of God that he was suffering because he had voluntarily charged himself with our sins.
Today, the angels bow to this mystery of divine love and are the object of their contemplation (1 Pet. 1:12). A multitude of the heavenly host praised God when he was born in Bethlehem (Luke 2:13). Now redemption is the subject of their joy : they rejoice and praise God when he saves a sinner (Luke 15: 7,10).
